mkimage: add atmelimage
The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel
ROM has no sophisticated image format, it only checks the first 7 ARM vectors.
The vectors can contain valid B or LDR opcodes, the 6'th vector contains the
image size to load.
Additionally the PMECC header can be written by the atmelimage target. The
parameters must be given via the -n switch as a coma separated list. For
example:
mkimage -T atmelimage \
-n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \
-d spl/u-boot-spl.bin boot.bin
A provided image can be checked for correct header setup. It prints out the
PMECC header parameters if it has one and the 6'th interrupt vector content.
